Interwubs

I recently began working for an engineering firm in downtown Portland, and we needed to move the Autodesk FlexLM licensing manager to a different server. While this is normally a straightforward process (Autodesk products will prompt you to enter the new server’s name), AutoCAD MEP 2009 & 2010 and Revit MEP 2010 failed to launch and reported FlexLM error 1200.5.-96:

According to Autodesk’s support website, this error indicates a failure to communicate with the license server, but since we had supposedly changed the licensing server when prompted by AutoCAD, this seemed to be erroneous.

As it turns out, the problem lies in the LICPATH.LIC file present in the programs’ directories. The file had somehow been locked into read-only mode, which was preventing AutoCad and Revit from updating it to point to the new server. Copying the file to the desktop, editing the copy to reflect the server change and overwriting the old file with the new instantly solved the problem. Bear in mind that each program will need to have its individual license file updated.
